Boc-NH-PEG3-OH (N-Boc-PEG3-alcohol, CAS: 139115-92-7) is a versatile PEG linker featuring a Boc-protected amine and a terminal hydroxyl group. The PEG3 spacer enhances solubility in aqueous media, making it suitable for various bioconjugation and drug delivery applications. The hydroxyl group allows for further derivatization or functionalization with reactive groups, while the Boc group can be easily removed under mild acidic conditions to reveal a free amine. As a cross-linking reagent, Boc-NH-PEG3-OH provides flexibility and utility in creating stable linkages, ideal for targeted bioconjugation and advanced synthesis projects.
